- Your team reconciles inventory, but the same discrepancies return. Shopify accepts an order a store can’t fulfill. Associates search for stock that has already sold, and the eCommerce team handles another cancellation. A fresh count can correct the balance. But if store sales, transfers, and online orders keep reaching connected systems late or being applied incorrectly, the next transaction starts the problem again. That’s why recurring inventory mismatches deserve more than another adjustment. They reveal a gap between what happens to stock and when the business stops promising it to shoppers.   ## Different numbers can be correct Shopify, NetSuite, and a point-of-sale (POS) system don’t always show the same inventory measure. A retailer may have 10 units on hand, with two committed to orders and two held back from sale. Six units are available to sell, even though all 10 are still physically present. Shopify distinguishes between [on-hand, available, committed, unavailable, and incoming inventory](https://help.shopify.com/en/manual/inventory-and-locations/fundamentals/inventory-states). Comparing an on-hand balance in one system with an available quantity in another can make a valid difference look like an error. A meaningful comparison concerns the same SKU, location, inventory measure, and point in time. The problem begins when a quantity no longer reflects the activity it should include, such as an available balance that still contains a unit sold at the register.   ## A recorded sale can still become an oversell Consider a store with two sellable units. One sells at the register. The other ships to another store. Both transactions are recorded, but neither update has reached the system supplying Shopify’s online availability. An online shopper places an order against stock that has already left. The store’s starting count was accurate. The transactions were recorded correctly. The failure occurred between those events and the change in online availability. This is how phantom stock can appear without anyone entering a wrong count. A unit remains available in a system after it has sold or moved. Even if the records agree later, the retailer still has an order it can’t fulfill as planned. The same risk extends to incoming transfers. Stock traveling between stores can’t fulfill an immediate pickup or shipment from the destination. Showing it as available before receipt creates another sale the store isn’t ready to complete.   ## Online orders claim inventory before it leaves the shelf Physical movement is only part of the story. An accepted online order creates demand while the item is still sitting in a store or warehouse. Shopify records that commitment within its inventory model. Across a connected retail network, the challenge is keeping the same demand accounted for as the order enters an order management system and waits for a fulfillment location. If a shared availability calculation overlooks that waiting order, another channel may promise stock that’s already committed. The gap is especially costly when several channels draw from a limited pool of stock. During a product launch or promotion, orders can arrive while earlier demand is still waiting for allocation. If that demand isn’t included in availability, each channel may appear to have stock even as the business has already committed the remaining units. The reservation must remain accounted for as the order moves through fulfillment, and be released if it’s canceled. Otherwise, a retailer can oversell stock already promised to a customer or keep canceled demand from returning to sale.   ## The cost goes beyond a canceled order When inventory can’t be trusted, store associates spend time searching for missing units and rejecting picks. Fulfillment teams try another location, and customer service explains delays or cancellations. A single discrepancy creates work across several teams. Repeated failures also change how retailers sell. An eCommerce team may increase buffers or stop offering inventory from stores with frequent failed picks. That reduces exposure to overselling, but it also hides stock that could have completed an online order. The retailer then loses sales in both directions: orders accepted against unavailable stock and orders never placed because sellable stock is hidden. Large buffers can contain the symptoms while leaving the underlying transaction gaps unresolved.   ## Why another inventory reset won’t keep the problem fixed Cycle counts remain necessary for finding missing, damaged, or incorrectly recorded stock. A full inventory reset can also bring an accumulated difference back into line. Neither correction, by itself, changes how the next sale or transfer reaches connected systems. If a sale is deducted twice, the corrected balance will drift again. If a transfer shipment arrives late, departed stock may remain available again. If a rejected pick doesn’t lead to an appropriate stock correction, the next order may send an associate back to search for the same missing item. Faster synchronization can shorten delays. It can’t resolve competing inventory updates or decide which quantity belongs online. Retailers need clear ownership of inventory changes and a consistent calculation of sellable availability across the order lifecycle. NetSuite can continue recording the inventory activity it owns, the POS can record store sales, and Shopify can capture online demand. The business also needs one authority for what remains sellable across those systems. That responsibility is what keeps separate records from becoming conflicting promises to shoppers.   ## How HotWax Commerce keeps online availability current HotWax Commerce combines inventory data from ERP, POS, and warehouse systems to [calculate Online ATP](https://docs.hotwax.co/documents/learn-hotwax-oms/business-process-models/inventory-lifecycle), the quantity available to promise online. It accounts for reserved demand, stock protected for store shoppers, and locations excluded from online selling. Accepted online orders reduce Online ATP while they wait for routing, before a fulfillment location is selected. Store receipts and approved cycle-count adjustments also feed the calculation, so availability reflects more than the latest physical stock balance. HotWax publishes the resulting sellable quantity to Shopify through the shop’s configured inventory synchronization process. How quickly a source change reaches the storefront still depends on the connected systems and their update schedules. This gives retailers a way to expose eligible store inventory online while accounting for the commitments and protections that make it sellable. The goal is fewer failed picks and cancellations, with less reliance on broad buffers that hide stock from shoppers. \*     \*     \*  [Talk to the HotWax Commerce team](https://www.hotwax.co/connect) about keeping Shopify availability aligned with store sales, inventory movements, and online demand. ## Related Blogs ### [![Store employee counting packaged stock, the physical QOH behind an inventory number shown online](https://www.hotwax.co/hs-fs/hubfs/blogs/why-your-inventory-number-needs-an-explanation-not-just-accuracy/Why%20Your%20Inventory%20Number%20Needs%20an%20Explanation%2c%20Not%20Just%20Accuracy%20banner%20img.png?width=960&height=498&name=Why%20Your%20Inventory%20Number%20Needs%20an%20Explanation%2c%20Not%20Just%20Accuracy%20banner%20img.png) Inventory Management Why Your Inventory Number Needs an Explanation, Not Just Accuracy](https://www.hotwax.co/blog/why-your-inventory-number-needs-an-explanation-not-just-accuracy) ### [![Empty store display shelves, the result when real-time inventory publishes stock that is not sellable](https://www.hotwax.co/hs-fs/hubfs/blogs/real-time-inventory-is-not-the-same-as-trustworthy-inventory/Real-Time%20Inventory%20Is%20Not%20the%20Same%20as%20Trustworthy%20Inventory.png?width=960&height=498&name=Real-Time%20Inventory%20Is%20Not%20the%20Same%20as%20Trustworthy%20Inventory.png) Inventory Management Real-Time Inventory Management: Why Sync Won't Stop Overselling](https://www.hotwax.co/blog/real-time-inventory-is-not-the-same-as-trustworthy-inventory) ### [![Road signs pointing to 'Sales Velocity' and 'Weeks of Supply,' illustrating retail order routing strategies for inventory management and store fulfillment optimization.](https://www.hotwax.co/hs-fs/hubfs/blogs/when-to-route-orders-by-sales-velocity-vs-weeks-of-supply/Sales%20velocity%20vs%20Weeks%20of%20supply%20banner.png?width=960&height=498&name=Sales%20velocity%20vs%20Weeks%20of%20supply%20banner.png) Inventory Management When to Route Orders by Sales Velocity vs Weeks of Supply](https://www.hotwax.co/blog/when-to-route-orders-by-sales-velocity-vs-weeks-of-supply) ### [![Empty store shelves, showing inventory on the shelf vs inventory that is actually for sale](https://www.hotwax.co/hs-fs/hubfs/blogs/inventory-on-the-shelf-vs-inventory-for-sale/inventory-on-shelf-vs-for-sale.png?width=960&height=498&name=inventory-on-shelf-vs-for-sale.png) Inventory Management Inventory on the Shelf vs Inventory for Sale: Why Stores Need Protection Rules](https://www.hotwax.co/blog/inventory-on-the-shelf-vs-inventory-for-sale-why-stores-need-protection-rules) ### [![Store associate scanning a barcode on a shipment box during inventory receiving](https://www.hotwax.co/hs-fs/hubfs/blogs/receiving-is-where-inventory-accuracy-is-decided/Receiving%20Is%20Where%20Inventory%20Accuracy%20Is%20Decided.png?width=960&height=498&name=Receiving%20Is%20Where%20Inventory%20Accuracy%20Is%20Decided.png) Inventory Management Inventory Receiving: Where Store Inventory Accuracy Is Decided](https://www.hotwax.co/blog/receiving-is-where-inventory-accuracy-is-decided) ### [![A hand stopping a row of dominoes from falling, illustrating the prevention of inventory errors.](https://www.hotwax.co/hs-fs/hubfs/blogs/a-people-first-approach-to-fixing-store-inventory-management/a-people-first-approach-to-fix-store-inventory-management.webp?width=960&height=498&name=a-people-first-approach-to-fix-store-inventory-management.webp) Inventory Management A People-First Approach to Fixing Store Inventory Management](https://www.hotwax.co/blog/a-people-first-approach-to-fixing-store-inventory-management) ### [![Associate scanning a box with a barcode scanner during an inventory cycle count in a stockroom](https://www.hotwax.co/hs-fs/hubfs/blogs/inventory-cycle-counts-guide/The%20Guide%20to%20Inventory%20Cycle%20Counts.png?width=960&height=498&name=The%20Guide%20to%20Inventory%20Cycle%20Counts.png) Inventory Management Cycle Counting: The Retail Guide to Inventory Cycle Counts](https://www.hotwax.co/blog/inventory-cycle-counts-guide) [![HotWax Commerce](https://www.hotwax.co/hubfs/Hotwax-2021/HotWax_February2020/Images%20Icons,%20Apparel%20background,%20Hexagon/logo-hotwax-dark.svg)](https://www.hotwax.co/) ### Connect ### Headquarters 175 S Main St Suite 1310, Salt Lake City, UT 84111 -
